Dumpling is a broad class of dishes that consist of pieces of cooked dough, often wrapped around a filling. The dough can be based on bread, wheat or other flours, or potatoes, and it may be filled with meat, fish, tofu, cheese, vegetables, or a combination. Dumplings may be prepared using a variety of cooking methods and are found in many world cuisines.

Dough is a thick, malleable, sometimes elastic paste made from grains or from leguminous or chestnut crops. Dough is typically made by mixing flour with a small amount of water or other liquid and sometimes includes yeast or other leavening agents, as well as ingredients such as fats or flavorings.
